This article explores youth development, social conflicts and unrest that often degenerates into violence and threaten Nigeria's sociopolitical stability, economic growth and development. In spite of the promises by the successive political leaders and policymakers that youth development will be given priority attention Nigeria has an army of unskilled, jobless and poverty-stricken youth who are prone to anti-social behavior and violence because many of them appear to lack home and community supports as well as economic opportunities. This article argues that investment in positive youth development programs is the key to empowering them with the skills and knowledge to grow into productive and responsible adults; it also helps to improve their living conditions, take care of others as well as to resolve social conflicts effectively. Drawing from available pertinent literature this article will, through descriptive design and in-depth analysis, recommend strategies to assess the efficacy of youth development programs and manage, control or resolve conflicts in Nigeria.
